1. Never Overtrade. To take an interest larger than
the capital justifies is to invite disaster. With such an
interest a fluctuation in the market unnerves the
operator, and his judgment becomes worthless.

2. Never “Double Up”; that is, never completely and
at once reverse a position. Being “long,” for instance,
do not “sell out” and go as much “short.” This may
occasionally succeed, but is very hazardous, for should
the market begin again to advance, the mind reverts
to its original opinion and the speculator “covers up”
and “goes long” again. Should this last change be
wrong, complete demoralization ensues. The change
in the original position should have been made moderately,
cautiously, thus keeping the judgment clear
and preserving the balance of the mind.

3. “Run Quickly,” or not at all; that is to say, act
promptly at the first approach of danger, but failing
to do this until others see the danger, hold on or close
out part of the “interest.”

4. Another rule is, when doubtful, reduce the amount
of the interest; for either the mind is not satisfied with
the position taken, or the interest is too large for
safety. One man told another that he could not sleep
on account of his position in the market; his friend
judiciously and laconically replied: “Sell down to a
sleeping point.”
